微量游离细胞的电镜包埋前的处理是个较棘手的问题。若处理不当会造成在以后的操作过程中细胞逐渐丢失。有关这方面的技术已有报道 [1— 3] ,但往往存在着步骤多或细胞分散、难切片等问题。本文介绍一种微量游离细胞包埋前的处理方法 ,操作步骤简单 ,细胞集中 ,利于切片。材料? Electrophoresis of trace free cells prior to embedding is a more troublesome problem. Improper handling can result in the gradual loss of cells during subsequent procedures. Techniques in this area have been reported [1-3], but often there are problems such as more or less cells and difficult to slice. This article describes a trace free cell embedding before treatment, simple steps, cell concentration, conducive to slicing. material?
